I tested some solutions, but without getting the simple results.
aesthetic I would like to use the arrows. rather than parentheses. the formula is followed by a text with explanations of the conditions.
would you have some simple suggestions about it?
thanks

  • @Bernard the equation I would like to explain is more complex. It is the conditions with respect to the production of buoyancy forces compared to the Richardson number.

My suggestion for example, for the 2nd formula, without left bracket, is with the package tikz-cd.
